Shot Blast your concrete floor

How to shot blast your concrete floor.

Shot Blasting is a surface treatment process using high velocity steel abrasive. Shot blasting is method through which it is possible to obtain excellent cleaning and surface preparation for secondary finishing operations. In general shot blasting concentrates abrasive particles at high speed (65-110 m/second) in a controlled manner at the material thereby removing surface contaminates due to the abrasive impact. Shot blasting is an affordable option, but it’s not the best choice for every circumstance. When shot blasting, the machine is required to overlap areas which results in blast lines. Even if a contractor is extremely careful, shot blasting can result in pits, valleys and fractures in the floor.

Shot blasting is extremely efficient when resurfacing industrial plants, parking garages and other commercial concrete floors and steel decks. Shot blasting uses mechanically propelled steel shot that is contained in housing over the concrete floor leaving an ideal surface for coating. As the steel shot blasts dirt, grime, old coatings, and embedded chemical contaminants from the concrete floor, they are continuously recycled and the pulverized concrete and contaminants are collected in the connected dust collector. Because shot blasting floors is a contained process, it is ideal in industrial settings with sensitive or difficult to move equipment.

Shot blasting can lightly clean or remove as much as a quarter inch of concrete depending on the size of the abrasive and duration of blasting.

Shot blasting can be beneficial where there is rain damage, surface stress, delaminating, improper curing, cured cold joints, joint shoulder failure or just wear and tear from years of use.
It can increase strength for a deteriorated and weakened concrete finishes with more abrasion resistance and an increase of impact resistance.
Shot blasting is by far the highest recommended method of preparing a substrate for any kind of coating or sealing. The increase of ambient lighting makes it environmentally friendly by reducing the cost of lighting as well as enhancing the beauty of your floor.
Shot blasting is useful for many industries, including the aerospace, ship building, forging and steel industries because it provides a consistent and uniformly fine, rough or matt surface depending on the techniques and tools used and the type of surface required.

Here are some of the major benefits associated with shot blasting as a surface preparation technique –

Shot blasting eliminates the usage of non-eco-friendly and harsh chemicals

Shot blasting provides higher production rates

Shot blasting facilitates the formation of a permanent bond between the protective coat and the shot blasted surface.

Shot blasting increases longevity and durability of protective surface coats as it adheres better to the shot blasted surface

Shot blasting is virtually dust free
